As a fellow PR, I would suggest getting +4 str/-4 con and +4 dex/-4 con tattoos for PvE, and sticking with your original stats or even boosting your con if you're already at a state where you're PvPing a lot.
Boosting your damage output is all you need to worry about while leveling, since when kiting you can easily support even a tiny hp value with cheap healing potions. As an archer you'll mainly be worried about mp efficiency, since you'll be resting for mp more than anything else.
For the purposes of PvP, damaging the low con of a dark elf makes you ridiculously easy to stun and even easier to take down. You'll probably be alright just sticking with normal stats, but boosting your con a bit will provide some needed stun resistance and increase your longevity while making your damage output suffer.
